How We Do Business
As part of our standard business practices, we have automated our Procure-to-Pay Process to improve operational efficiency and cost effectiveness. This is done through procurement tools and applications, i.e. Ariba Network. The Ariba Supplier Network is used by Waste Management to send purchase orders and to receive invoices from suppliers. By implementing this tool, we have streamlined our work processes and payments to suppliers within contract terms.
